I am an observational extragalactic astronomer with interests in galaxy evolution and large-scale structure. I employ tools such as gravitational lensing to trace distributions of dark matter on large scales, and I use multiwavelength observations to examine the luminous properties of galaxies. With the goal of linking galaxy properties with detailed knowledge of their environments, I am leading the STAGES survey: a 0.5x0.5 degree HST/ACS survey of the A901/902 supercluster to study galaxy evolution in dense environments. We are measuring the morphologies, star-formation activity, and AGN content of over 1200 galaxies in a massive structure at z=0.17 while simultaneously measuring the distributions of dark matter, hot gas, and galaxies in which those galaxies are embedded.Current TeachingF34AP9 Image processing
